Abstract
A decoration member including: a color developing layer including a light reflective layer and a light absorbing layer provided on the light reflective layer; and a substrate provided on one surface of the color developing layer. The substrate includes a pattern layer, and the light absorbing layer includes silicon (Si).
Claims
exact text as granted — not AI-modifiedThe invention claimed is:
1. A decoration member comprising:
a color developing layer comprising a light reflective layer and a light absorbing layer provided on the light reflective layer; and
a substrate provided on a surface of the color developing layer,
wherein the substrate comprises a pattern layer,
wherein the light absorbing layer comprises silicon (Si), and
wherein a cool tone parameter σ is represented by following Equation 1 and σ is greater than 0 and less than or equal to 0.7:
σ=( T x )×( T y ) [Equation 1]
wherein in Equation 1, T x is represented by Equation 2, and Ty is represented by Equation 3:

and T 0 is 60 nm;
wherein when T 1 is not m*T 0 +10 nm, T x satisfies Equation 2, and when T 1 is m*T 0 +10 nm, Tx is 1,
wherein m is an integer of 1 or greater; and
wherein T 1 is an average thickness of a cross-section of the light absorbing layer in a thickness direction of the decoration member, and T 2 is an average thickness across-section of the light reflective layer in a thickness direction of the decoration member,
wherein Tx is greater than 0 and less than or equal to 0.5,
wherein Ty is greater than 1.0 and less than or equal to 1.4,
wherein a thickness of the light absorbing layer is 10 nm to 300 nm, and
wherein a thickness of the light reflective layer is 1 nm to 100 nm.
2. The decoration member of claim 1 , wherein a hue-angle h* in CIE LCh color space of the light absorbing layer is in a range of 105° to 315°.
3. The decoration member of claim 1 , wherein the light reflective layer is a single layer or a multilayer comprising one, or more materials selected from the group consisting of indium (In), titanium (Ti), tin (Sn), silicon (Si), germanium (Ge), aluminum (Al), copper (Cu), nickel (Ni), vanadium (V), tungsten (W), tantalum (Ta), molybdenum (Mo), neodymium (Nd), iron (Fe), chromium (Cr), cobalt (Co), gold (Au) silver (Ag); oxides thereof, nitrides thereof; oxynitrides thereof; carbon and carbon composites.
4. The decoration member of claim 1 , wherein the light absorbing layer has a refractive index of 0 to 8 at a wavelength of 400 nm.
5. The decoration member of claim 1 , wherein the light absorbing layer has an extinction coefficient greater than 0 and less than or equal to 4 at a wavelength of 400 nm.
6. The decoration member of claim 1 , wherein the light absorbing layer comprises two or more points with different thicknesses.
7. The decoration member of claim 1 , wherein the color developing layer further comprises a color film.
8. The decoration member of claim 1 , wherein the pattern layer comprises a convex portion or a concave portion shape having an asymmetric-structured cross-section.
9. The decoration member of claim 1 , which has dichroism of ΔE*ab>1, wherein (ΔE*ab) is a distance in a L*a*b* space in a color coordinate CIE L*a*b*, L* is a distance from L axis and a* and b* are Cartesian coordinate.
10. The decoration member of claim 1 , wherein the substrate is a plastic injection molded article or a glass substrate for a cosmetic container.
11. The decoration member of claim 10 , wherein the plastic injection molded article comprises one or more materials selected from the group consisting of polypropylene (PP), polystyrene (PS), polyvinyl acetate (PVAc), polyacrylate, polyethylene terephthalate (PET), polyvinyl chloride (PVC), polymethyl methacrylate (PMMA), an ethylene-vinyl acetate copolymer (EVA), polycarbonate (PC), polyamide and a styrene-acrylonitrile copolymer (SAN).Cited by (0)
